CLASSIFICATION OF METASOMATIC ROCKS AND FACIES OF SHALLOW METASOMATISM

International Geology Review, 1992
The authors present a dual but parallel classification of metasomatic rock types and metasomatic facies. The classification may make clearer to Westerners the meaning of some terms (eysite, secondary quartzite, etc.) used extensively only in the Russian literature.

Geochronology of Metasomatic Events

2012
In order to date any geological event, suitable mineral geochronometers that record that and only that event must be identified and analyzed. In the case of metasomatism, recrystallisation is a key process that controls both the petrology and the isotopic record of minerals. It can occur both in the form of complete neocrystallisation (e.g.

METASOMATISM OF THE MAYKHURA GRANITES

International Geology Review, 1964
Post-magmatic metasomatism of Maykhura granites has produced two distinctive zonal sequences (in increasing degree of alteration) as follows: Sequence (A) of 1) unaltered granodiorite, 2) muscovite granodiorite, 3) tourmaline granite, 4) muscovite granite, 5) orthoclase granite, 6) quartzalbite granite, and 7) monomineralic quartz rock.

Metasomatism and ophiolitic rocks

2022
Τα σερπεντινιωμένα υπερβασικά πετρώματα της Κεντρικής Εύβοιας εμφανίζονται στις περιοχές της Κύμης και του Παγώντα και χαρακτηρίζονται από διεισδύσεις φλεβών ροδιγκίτη. Οι εν λόγω ροδιγκίτες διακρίνονται στους ακόλουθους τέσσερις τύπους ανάλογα με τους πρωτόλιθους από τους οποίους προήλθαν: (i) ροδιγκίτες θολειϊτικών δολεριτών τύπου νησιώτικου τόξου ...

The theory of metasomatic zoning

Mineralium Deposita, 1968
The main features of the theory of metasomatic zoning, developed by the author, are here exposed. The basic differential equations of metasomatic zoning, of the infiltration as well as of the diffusion type, are deduced for the conditions of local equilibrium, the kinetic phenomena being neglected.

Metasomatism and Intrusion in Jamaica

Geological Magazine, 1942
The nearest known pre-Cretaceous rocks to Jamaica are Jurassic in Western Cuba, and Carboniferous in Colombia, Venezuela, and Honduras, all about 500 miles away. The evolution of Jamaica seems to have been somewhat as follows. Andine (?) orogenesis on or near the site took place, accompanied by magmatic invasion; the rocks are nowhere seen “in situ ...
